“…M esenchymal stem/stromal cells (MSCs) are multipotent cells, which are able to give rise to fibroblast-like colonies [colony-forming units-fibroblasts (CFU-F)] [1,2] and to differentiate into mesodermally derived tissues, including bone, cartilage, muscle, stromal cells, tendon, and connective tissue [3][4][5][6][7]. Cultured MSCs are well-characterized spindleshaped cells that express a panel of key surface markers, including CD29, CD73, CD90, CD105, CD106, CD140b, and CD166, but lack CD31, CD45, CD34, CD133, and class II MHC expression [8][9][10].…”
